NPDES Pesticide General Permit In October 2012, the DOH issued a NPDES General Permit to authorize point source discharges from the application of pesticides (including insecticides, herbicides, fungicides, rodenticides, and various other substances to control pests) to State waters. This NPDES Pesticide General Permit (PGP) is in Hawaii Administrative Rules (HAR), Chapter 11-55, Appendix M. You may download HAR 11-55 from the DOH-CWB website at: http://health.hawaii.gov/cwb/
